Open a TestStand report and actually read it
An NI TestStand ATML report is a 1–2 MB XML file. Opening one in a browser or a text editor gives you a wall of namespaces and attributes; opening it in TestStand means having TestStand on that machine. Report Viewer is a small standalone Windows application that opens a single report and shows it as what it is: a header with the run information, and a clean table of every test step.
It is completely free. No license key, no account, no registration, no trial period and no feature locked behind a purchase.
A report open in Report Viewer. The header carries the run information — sequence, start and end time, duration, overall result, operator, station, UUT serial, product and step totals — and below it every step with its limits, measured result, comparison type and status. 919 steps, searchable, with a single toggle to show only the failures.

What it does
- Opens one report, three ways — from the File menu, by dragging the XML file onto the window, or by right-clicking the file in Windows and choosing Open with.
- Run information at a glance — sequence, start and end time, duration, overall outcome, operator, test station, UUT serial number, test socket index, product and run index.
- A readable step table — name, lower limit, measured result, upper limit, comparison type, status and any additional results, with units shown next to the values.
- Find what failed — search by step name and a single toggle that hides everything except failures, with a live row count.
- Recent files — the last eight reports you opened, one click away.
- Signal, not noise — setup and cleanup SessionActions are excluded, so the table shows only real test steps: NumericLimitTest, NI_MultipleNumericLimitTest, PassFailTest and StringValueTest.
- Light and dark themes.
What it does not do
Report Viewer reads one report at a time. It does not calculate statistics, does not compare runs, and does not export anything — it is a viewer, deliberately.
If you need capability studies, trends across hundreds of executions, error Pareto analysis or PDF and Excel reports, that is Report Analyzer, our paid tool for the same report format.

Questions
Do I need NI TestStand installed?
No. Report Viewer only reads the XML report files TestStand produces, so it runs on any Windows PC — including an office machine that has never had TestStand on it.
Does anything leave my computer?
No. The file is parsed locally and nothing is transmitted. The application works with no internet connection.
Is it really free, or does it stop working later?
Really free. There is no trial timer and no activation screen.
Why give it away?
Because most people who open a TestStand report just need to read it. If you later need to analyze hundreds of them, you will already know who we are.
